Likes and favourite item search and storage

Elastic Stack Elasticsearch
1

Hi,

I'm looking for the best practise for recording 'likes' of an item.

If I have a document

{
'name' : 'Dave',
'age' : 40,
'album' : 'foo'
}

If people decide to 'like' 'Daves' album 'foo'. Where is the best place to
store these 'likes'? in the document?

{
'name' : 'Dave',
'age' : 40,
'album' : 'foo',
'likes' : {
'user1',
'user2',
}
}

Or store the likes in a different type? Because When I return results for
albums, Dave's album should rank higher because that album has more likes.
But also I want to show how many likes the album has. But with people
liking and un-liking albums, I want to avoid conflicts with updates.

So what is the best approach? Should I put everything into a queue? How
will I query and arrange by number of likes if the documents are separated?

Thanks.
